VOICE PROCESSOR AND VOICE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a voice signal processing technique for generating natural voice sound having various characteristics.

SOLUTION: A generating means 10 generates voice a signal Sa having a period Ta. A distributing means 20 distributes the voice signal Sa generated by the generating means 10 into first and second systems. A delaying means 30 delays a voice signal Sa1 of the first system with respect to a voice signal Sa2 of the second system so that the phase difference between a voice signal Sb1 of the first system and a voice signal Sb2 of the second system becomes the phase difference corresponding to the added value or the difference value of a first time length L1 that is approximately one half of the period Ta of the voice signal Sa and a second time length L2 that is shorter than the first time length L1. An amplifying means 40 amplifies the voice signal Sb1 and Sb2 so that the amplitude ratio of a voice signal Sc1 of the first system to a voice signal Sc2 of the second system becomes a prescribed numerical value. An adding means 50 adds the voice signals Sc1 and Sc2 and outputs the added signals.
